NaNs in HMI chart

[Matt]

Hi,

I'm building an HMI with a chart in it. The chart is plotting a few values that I set to NaN when there are communication errors, etc. The problem is that the chart doesn't appear to handle NaNs correctly--it just interprets them as something like -5*10^38 and ruins the scaling on the vertical axis. Is there a way to perhaps have the chart ignore NaN values or otherwise pass it blank values?

Thanks,
Matt

Hi @matt,
sorry, still no update. I pushed the developers a bit.

@martin-kudláček Okay, thanks. After posting yesterday I managed to figure out the communication errors I was getting, so preventing the NaNs from messing up the chart is less of an issue now.
